Quantum Cryptography is a novel approach to make the information and network world more se- cure. Unlike classical cryptography, quantum cryp- tography ensures the security of communication be- cause it is based on the laws of Quantum Mechan- ics; a branch of physics that deals with the fun- damental behavior of matter and their energies to the levels of subatomic particles. These particles and their intrinsic properties such as photon po- larization and entanglement allow us to develop an unbreakable system of cryptographic informa- tion. Conventionally, the security has been primar- ily concerned with the secured distribution of se- cret key carried over an insecure channel. How- ever, in Quantum Cryptographic systems the trans- mission of secret key is done using aforementioned laws of nature through a secured quantum channel highly susceptible to intrusion detection. Conse- quently, the Quantum Key Distribution (QKD), in conjunction with protocols such as BB84 protocol has emerged as an ultimate modern secured com- munication system. This article concentrates on briefly reviewing quantum cryptography, some re- cent developments and reports of its vulnerabilities.
